This can be factored as a difference of two squares. When you have a difference of two squares (a² - b²), it will factor out into (a + b) (a - b).

(x² - r²)
(x + r)(x - r)

You can multiply the two groups to double check it.

(x + r)(x - r)
x² - rx + rx - r²
x² - r²

For this type of question, we have to take out the percentage of each candidate:

For Arthur

85 from 95

Convert   95 to 100

That means that we have to add 5, do the same thing with 85. Add 5 to 85 and you get 90. That means Arthur got  90% For Miguel 64 from  76. Covert 76 to 100. That means we have to add 24. Do the same thing with 64. Add 24 + 64. It equals 88% Miguel got 88%
